Acid2 is a webpage that tests web browsers' functionality in displaying aspects of HTML markup, CSS 2.1 styling, PNG images, and data URIs. The test page was released on 13 April 2005 by the Web Standards Project. The Acid2 test page will be displayed correctly in any application that follows the World Wide Web Consortium and Internet Engineering Task Force specifications for these technologies. These specifications are known as web standards because they describe how technologies used on the web are expected to function.

It was developed in October 1998 and was important in establishing baseline interoperability between early web browsers, especially for the Cascading Style Sheets 1.0 specification. As with acid tests for gold which produce a quick and obvious assessment of the quality of a piece of metal, the web acid tests were designed to produce a clear indication of a browser's compliance to web standard

The 3DBenchy is a 3D computer model specifically designed for testing the accuracy and capabilities of 3D printers. It is described by its creators Daniel Norée and Paulo Kiefe, at the time employees of Creative Tools, as "the jolly 3D printing torture-test" and was released (initially only in STL format) in April 2015, with a multi-part, multi-colour model released in July 2015.
